It might have a little in it from the factory but i have alot in there can it be that the PCV is no good also he did disconnect every polution device...air pump...everything...So im wondering if the motor is building up to much vac and is sucking oil thru the PCV into the carb making it smoke...What i did is put a new PCV valve in and disconnected the breather tube that goes to the filter i left it opened like an older system were it had one pcv and a breather on the other valve cover it seemed to help alot....wonder if im on the right track???

Most of the time all new exhuast, headers to tailpipes that are "new" not used will smoke as they heat up. During the manurfacturing process of pretty much any bent, stamped or worked with force is coated in oil to aid in the process as well as being a rust protection sheild.

If your exhaust is still smoking in 4-6 days from the instal then I would be worried. If I were you I would go on a nice long drive on the highway and let it all burn off.
